WINDOW-LOCK.

Application filed July 2 1, 1919.

To all whom it may concern:

Be it known that I, RAY BELLINGER, a citizen of the United States, and a resident of Chicopee Falls in the county of Hampden and State of Massachusetts, havemade certain new and useful Improvements in.

VVindow-Locks, of which the following is a specification.

My invention relates to window locks, and a purpose of my invention is the provision of a device of this character which will lock a window in closed position or in anyone of several open positions so as to secure ventilation at the top or bottom of the window or both. 7

It is also a purpose of my invention to provide a window lock which when in locking position prevents rattling of the window.

I will describe one form of window lock embodying my invention, and will then point out the novel features thereof in claim.

In the accompanying drawings Figure 1 is a view showing in front elevation a conventional form of window having applied thereto one form of locking device embodying my invention.

Fig. 2 is a vertical sectional view of the window shown in Fig. 1 showing the lock in side elevation.

Fig. 3 is a sectional view taken on the line 3-3 of Fig. 1.

Fig. 4 is a view showing in bottom plan, the locking member in releasing position.

Fig. 5 is a view similar to Fig. 1, showing the locking member in looking position.

Fig. 6 is a transverse sectional view of the locking member taken on the line 66 of Fig. 3.

Similar reference characters refer to similar parts in each of the several views.

Referring specifically to the drawing, W designates generally a conventional form of sliding window comprising an upper sash S and a lower sash S. The lower sash S is provided on its upper edge with a locking member designated generally at M which coacts with a keeper K secured to the upper sash S for locking both of the sashes against movement relatively.

The locking member M comprises a casing 15 formed of suitable metal and provided with openings 16 to receive screws 17 for securing the same to the sash S.

-As shown in Figs. 4 and 5, the underside Specification of Letters Patent. Patentd 'Apr, 27, 1920.

Serial No. 312,918.

of the casing 15 is open but is closed when in applied position by the wall of the sash S. Arranged on the upper side of the casing 15 is a locking lever or bolt 18 which is formed at one end with a bill 19 having an inclined edge 19*. The opposite end of the lever 18 is bent to provide an operating handle H, while adjacent the handle, the lever is provided at opposite points with depending arms 20 and 20 which extend through a circular aperture formed in the casing 15, as shown in Fig. 6. The lower ends of the arms 20 and 20 are formed with I lugs 21 which extend through and are upset to support a disk 22 disposed within the casing.

Extending longitudinally within the easing 15 are a pair of leaf springs 23 and 23 which have their opposite ends bent at an angle so as to abut the end walls of the casing. These springs 23 and 23 are disposed in the path of movement of the arms 20 and 20, so that when the locking lever 18 occupies a releasing position, the springs frictionally engage the arms and serve to bias the lever to the releasing position.

As shown in Fig. 3, the keeper K is secured to the inner side of the upper sash S and comprises a channel bar 24} cut to conform to the contour of the sash wall and formed at spaced intervals with holes 25 shaped to receive the bill 19 of the lever 18, as clearly shown in Fig. 2.

In practice, the lever 18 occupies the position shown in Fig. 4:, which is the releasing position of the lock, and is frictionally held in this position by the springs 23 and .23 as previously described. \Vhen it is desired to lock the sashes against rela tive movement, the lever is swung to the locking position as shown in Fig. 3, wherein the bill 19 moves into one of the holes 25. During movement of the lever from releasing to locking position, the arms 20 and 20 disengage the springs 23 and 23" so that they occupy substantially parallel positions, as shown in Fig. 5.

Because of the inclination of the edge 19"* of the bill 19, the lever 18 when moving into locking position draws the two sashes laterally toward each other, so that they are firmly held against rattling.

Although I have herein shown and described only one form of window lock embodying my invention, it is to be understood that various changes and modifications may be made herein without departing from the spirit of the invention, and the spirit and scope of the appended claim.

I claim A window lock, comprising a keeper including a channel bar having openings formed therein at intervals, a locking member including a casing, a lever, arms formed on said lever and extending through 10 said casing, springs mounted in said casing and engageable with said arms, a disk secured to said arms and disposed within said casing, a bill formed on said lever and adapted to be inserted in any one of the openings in said keeper, said bill being formed with an inclined edge which engages one of the walls of said openings, and a handle formed on said lever for actuating the same.

RAY BELLINGER.
